[Intel Iris graphics]

Ok thank you drobbins, I have removed the gfxcard-intel mix-in.

By cons I do not know how to register on bugs.funtoo.org to post the emerge error for the wpebackend-fdo package in bug FL-7195 for core-gl-kit.

[Intel Iris graphics]

In response to drobbins about installing the new Intel Iris graphic driver, I can't uninstall the xf86-intel-driver package even when hiding it. By cons I can uninstall xf86-video-fbdev.
Also, I have an installation error of the wpebackend-fdo package:

* ERROR: gui-libs / wpebackend-fdo-1.6.0 :: core-gl-kit failed (prepare phase):
* patch -p1 failed with /var/tmp/portage/gui-libs/wpebackend-fdo-1.6.0/files/1.6.0-eglmesaext-include.patch

Regards.
